Pinions 21, carried on the shaft 22,

mesh with the racks-20and are in turn driven 7 by a motor 23 through worm gearing 24, pinion and :gear 26 .which is secured to the shaft 22. :The worm 24 is se'c ured to the armature shaft of the motor 2:3 and-meshe's with a worm wheel 27 Carrie-don ajack 'shaft28 I mounted bearings 29-sup'ported by brackets 30 secured tofthe 'casing ofthe-motor 23. It

is apparentj-that rotation of the'motor 23 will rocklevers-19 about-the axle 6 with a slow powerful movement and that thelevers will be held in any position toifjwhich they are moved 'by theworm-24 and worm wheel 27. The forward ends of-the levers -19 carry a provided with a heavy 'arcuate ribor bead 32, shown best in Figs. 5'and 11. The web 31 and the bead 32 both extend to a considerable distance on either side of the levers 19. Supporting brackets 33 extend downwardly at the outer-edges of the web 31 a sufficient distance to rest upon the surface of the earth when the forward endsof the levers 19 arein theirlowermost position, as shown inFig. 5.

'- Thefront conveyer section C is carried by 'the forward truck A and has a front and ally mounted on a shaft36lcarriedin a yoke 37 which is provided with a slide support38 resting upon an arcuateslideway 39'formed on the upper endsof standards 40 which prov jectlupwardly from the main frame l fo'f the truck. When the conveyer section C is raised or lowered it moves about the shaft 136.as=an axis. The yoke 37 extends. rearwardly, as

42 connected" with the conveyer section 1). The bearing slides38 and '39. are curved about the axis ofthe pin 41 as a center sothat the conveyer section C may be swung from side to side aboutthepm 41 asan axis. t V Lateral swinging of the" conveyer section C iseflz'ected bya motor 45,Fig. "11', mounted on a plate 46 supported between the-leverbars.

The motor providesa worm 47 which meshes with a worm wheel 48, secured to an upright shaft 49 j ournaled'in a vertical-bean" ing in the plate 46 and carrying a drum secured to its lower end beneath the plate. A pair of-cables 51-and 52 have their ends secured to this drum and pass around pulleys .53 and 54 respectively journaled at the opposite edges of theplate 31. The cables-51 and 5231'8 carried backwardly from their respec-v tivepulleys and connected to lugs 55 and 56 formed on the frame of'the conveyer C, a I pornonbf which is shown in broken lines 7 in Fig, 11. :Itv isapparent that .by' this arrangement, rotation of the motor 45 in one direction iwill shiftethea conveyer section C to the left, while rotation of the .motor in the opposite direction willsliiftlthe conveyer to. the right; During thisjshifting movement the arcuatenotch 34 in :the conveyer frame slidesupon its-supporting rib 7 The conveyor sectioniC, as 'shown'lin Fig; 12, is madeup of a lowerfbedplate-57.which is bent upwardly to form side walls 58 and rebent downwardly-and inwardly to form inclined-plates 59 which carry horizontal flanges 60st their lower edgesQ Ansupper bed plate 61 is secured to the sidewalls 5 8 and is spaced a sufficient distance above the plate 57 toform a casing for thelower run'of the conveyor 62whichis madeup of chains 63 and cross slats or flights 64. The upper plate61 is secured-to the-sides'58-by angle. bars 65 and is also connected to the flanges 60 by angle bar s#66.' The front endof theconveyer G,

as shown inFigs. 5 and 6, is provided with a detachable section Ewhichforms a scoop for receiving -material to r be loaded. This l section; as shown best in *Fig. '19, has its side walls extended laterallyand fis provided at its front end with .a shoe' 67 which maybe forced-beneath the material to be loaded; 5 A1 roller 68 is journaled' inthe shoe 67 and the forward en'ds-of the conveyer chains 63 pass 7 around this roller. The scoop section B is provided witha suitable framework 69 which 1 is secured to the main-portion ofthe conveyer sectionObyineansof'bolts 70; The frame 69- is so shaped that its-lower surface rests squarely upon'thesurface of the ground when the conveyer istilted-downwardly, as shown in Fig. 5, thus forming'a, bearing for support- 'ingthe-front end of the conveyer upon the s'urface from which the-material is received. 1 The chainiconveyer 63 at itsrear end, passesi over a rolleron the shaft 36, as shownin Fig.4. The lower "runs of the chains pass over sprockets 71 which are secured to a shaft 7 2 rotatively mounted inbearingscarrie d by theiconveyer. frame.

rear truck frame is centrally'parted and is secured together by lugs 79 and bolts 80 and by anelongated bolt 81at the rear end of theframe. This permits the extensions 77 and 8 to be assembledin place about the framering 8 of the forward truck. The rear truck frame is provided with a bed plate-82, similar to the bed plate 4 of the forward truck but parted alongits center as previ-' ously stated. Wheels 83are securedto axles 84 and 85 journaled in the frame members 75 and 76, and the forward axle 8l'is'driven by a motor 87 provided with a pinion 88' which meshes with a gear 89 secured to the axle 84.-

A shaft 90 is journaled in "bearings 91 and 92 formed in the side members .75 and '7 6 re spectively, and this shaft'carries a series of drums 93, 94, 95 and 96; The shaft is driven from a motor 97 secured to the bed plate 82' of the truck frame and provided with" reduction gearing 98 by means. of which it is connectedwith the shaft 90. As shown inFigs.

the. frame ring 8is provided with a series of openings 103'whichreceive a pinor bolt 104;

carried by the extension 78 of the rear truck frame. The bolt 104: is pressed inwardlyby a spring 105- carried in a housing 106 secured to theextension 78, but may beheld in withdrawn-or retracted position by placing the bent ,end 1070f the bolt'in position to rest uponthe stop 108. carried by the housing 106.":1 number of holes 103is providedso' that the two trucks maybe locked in various angular positions relative to one another.

The rear conveyer section D is provided at Y its forward or receiving end withahopper brackets 112, Figs. 3 and 13, which have roll-j 110 which is pivotally secured to the circniarv web9 of'the framering 8 of. the maintru ck by means of a pivot pin 111. The hopper 110 'i hasits forwardportion positioned to receive material discharged from the front conveyer 1 section 0. The conveyer is provided, :adja

cent the rear portion of the truck B, with ers v 113 journaled thereon and arranged to travel on an arcuate track 114: supported on upwardly projecting lugs 115 carried by the main frame of the'truck. The brackets 112 also support amotor 116 which drives a shaft 117 carrying sprocket wheels 118 arrangcdto 119 which are provided with'fii hts 120 for moving the material over the rear conveyer D. The conveyersection Dis provided with a-vertically swinging extension'121 pivotaliy secured to the main portionof the conveyer at 122 and I provided with forwardly extende ing arms 123 whichfare pivotally connected at 12 1 with threaded rods 125 which "pass through openings in lugs 126 secured tothe Coil springs sides of the conveyer frame. 127 surround the ends of the rods 125 beneath the lugs 126 andrest upon the upper surface of hand wheels 128 which'engage the threads on the rods 125 and by means of which the tension of the springs, 127 may be adjusted to raise or lower 1 therear end'of the adjustable conveyer section;-

, It should be noted that by :locating the.

driving sprocket wheels 118 in front of the position whichthe mine car 129 assumes under the overhanging portion 121 of the conveyer, thechains 119 are drawn taut so as to prevent them from sagging down againstthe forward wallof the mine car.

The conveyer section 7 Dis provided with upper and lower bedplates 1 for the-different runs of the conveyer as shown in Fig. 13; the construction, being simi. lar to that describedin connection with the conveyer' section G;

A series'ofcontrollers130 are mounted on I I the yoke37 which carries-the forward convey'er section C in a position adjacent the operators platform 12. These controllers govern the various motorswhich drive the dif-. ferent parts of the machine,,but separate controllers need not be providedfor the two traction motors 13 and 87, sincethese motors opsrate'in unison with one another and maybe governed by a single controller. A supple mentary. controller'131, for theQ-motor 116 which drives the rear conveyor, is preferably mounted on the r'ear'portion of this conveyer and connected in parallel with the controller 130' for this motor so that'the rearconveyer may be, governed either from the operatorls r their inner ends pivoted together at 136 and,

For shifting the machine forwardly or :earwardly during loading operations, forwardly extending cables 132 are secured to the drums 93 and,96,-and rearwardly extending cables 133 are secured to the drums 94 and 9.5. The ends of the cables 132 are at cached at 134, Fig. 99,;to wall. jacks 135 having having their outer ends pivoted to. blocks 137 jacks 135 are inclined forwardly sol as to form a toggle to force the j acksinto contact with the walls of the-chamber and prevent rearwardmovement.

In Figs; 14 to 17 .inclusive,-there is shown I whichhas a downwardly extending circular I slideway 152. arranged to receive a sliding provided with a shoe Figs. 16 and 17 which :may be forced beneath material to be loaded. The'frame150 carries aroller 156 within'the hopper1151 over which roller the, I "conveyer-chains 63 pass Supportedby the frame'15O in. the spacebeneath. the conveyer 63 is'a motorf1'57'which1 drives a drum 1,58

A cable 160 is given one or two turns about the drum-158 and has its-ends ,secure'd f'to lugs 161" projecti v u ing from the outerperiphery of the slide ring mese 153. 7 By driving the motor 15 7, the conveyer section 154 may be shifted to.,either side of the hopper 151 so that the receiving section 154 may be directed. laterally relativeto thebeneath the material and thus the device may] main portion of the conveyer. When the receiving section 154 is so. directechthe main portion C of the conveyer may be swung sidewise upon its support to force the shoe 155 be made to pick up material by sidewise movement, thus materially extending the field of operation of the loading machine relative to the track upon which it is carried. The receiving-portion 154 is provided with a conveyer 162 which is driven' by a motor 163. through gearing 164 and, sprocket wheels 165. The conveyer 162 is arranged to discharge into the hopper 151for all positions of'the receiving section. 1 In operation current is supplied to themachine in any well known manner and the device is moved tothe point where loading is to be carried on by means of thetwo driving motors 13 and 87 ,the machine traveling upon a track which has been previously'laid to a' pointadjacent the material to be loaded.

Durin this transportation, the forward coni is supported in an elevated position,- as shown in broken lines in Fig. 2, and the weight of the conveyer is carried by the front veyer b truck. During such transportation also the catch 104 may be withdrawn tovpermit shifting of the two trucks relative to one another so that the machine may pass readily around comparatively sharp turns in the track. 1 After the machine has thus been brought'to the scene of operation, the wall jacks 135 j-are placed in position and the cables l32 secured to them. In likemanner, the clamps 138 are secured to the rails in the rear of the machine and the cables 133 fastened to the clamps.

The conveyer section is now lowereduntil its bottom surface rests upon'the surface upon which the material to be loaded is supported and'the drums 93 and 96 are driven to move the machine forwardly and force theshoe' 65 beneath the material. During this. move ment, the conveyer sections G andD are oper- .ated to carry thematerial rearwardly and discharge it into the car 129. Theconveyer' section C is, not limited to the field imme- "diately in front of the machine but the section may be swung to either side, as shown-in Fig. 1, and thus pickup the material from aconsiderable range. vIf a still: greater'lateral.

The ribbed end of the levers 19,- resting in the. groove 34,"positively holds the forward end of the conveyer downwardly upon the surface from which the material is beingremovedand prevents the con veyerfrom riding overithe material. When the conveyer is swung to one side or the other, the Weight ofthe truck is transmitted to the supporting surface by thedownwardly struck A upon the track, but the machine may be moved forwardly, until this truck is carried' entirely beyond the end of V the track. VVhen the machine is in this position, the

and 'thus any tendencyofthe machine to tip is overcome. The machine may thus be operateda very considerable'distance in advance of the track, the only requirement beingthat the, rear truckshall remain upon the track;

- Thefdis'charge' conveyer D. -may be moved manually fromside to side to distribute the load inthetran'sporting car, the hopper at,

the forward end, of'the conveyer remaining always in: position, to receive the material from' the forward conveyer and since the forward conveyer swings from side to side about thesame axis as the rear conveyer, it will always be in position to discharge into the hopper. The twoic'onveyers havethe same pivotalaxis asthat of; the two trucks'so' that during transportation the'entire machine has a single pivotal axis at its central'portion to permit easy jturning, about sharp corners.
